My real question, though, is:
She currently has EndNote X5 on those 3 computers, but the 3 installations are currently on two different licenses (L1 and L2), due to a mistake on the part of our long-gone IT guy.
She would like to upgrade to X7, but obviously doesn’t want to buy 2 upgrades if she only needs 1.
To install X7 on these 3 exisiting personal X5 installations, will she need to enter in matching serial numbers from both exisiting licenses (L1 and L2)?
Or, moving forward, can she just use L1’s serial number for these 3 upgrades (and future upgrades)?
More to the point…what actually happens when you run the upgrade? It seems like it does not actually modify the existing installation, but just asks you for your serial number. If that is the case, then it seems that she can just enter her actual serial number (L1) when she installs the software on all 3 of her computers – and she will forget about L2, and from now on, “her” serial number will perpetually be L1. I think.
